Title: Arrangement for carrying out random selection among a plurality of selectable devices in a telecommunication system
IPC: H04Q3/00
Filed: 1976-10-16
Abstract: Arrangement in a telecommunication system for random choice of one of a number of selectable devices, the condition of which is marked by the condition of a marking wire connected to the respective device. The selection is made by a selector chain consisting of a number of selector circuits each connected to its own wire. Activation of one of the circuits in the chain prevents the other circuits in the chain from activating, in order to cause that only one device at a time can be choosen. Each selector circuit contains a logic circuit with bistable characteristics. To the input of each selector circuit is connected a gate circuit which is activated on a first input by a signal from a marking wire and on a second input by a pulse from a pulse oscillator individual for each gate circuit. The pulse oscillators are working on slightly different frequencies and thus delivering signals at different moments. When the gate circuit is activated, said signal from the marking wire is forwarded to the selector circuit. That one of the selector circuits which first has received said marking wire signal will then be choosen and the device associated with said selector circuit will be occupied. The random choice is determined by a combination of the time for the call and by the moment in which a pulse from a pulse oscillator occurs.

Title: Method and apparatus for producing high purity silicon from flames of alkalimetal and silicon halide.
IPC: C01B33/027
Filed: 1981-10-16
Abstract: Vaporized silicon tetrachloride is mixed with vaporized sodium in an exothermic reaction producing liquid silicon droplets and gaseous sodium chloride which are subsequently separated in an efficient manner. Separation of the silicon from the salt by-products is performed by a jet impaction separation technique wherein the products of the complete reaction between sodium and silicon tetrachloride are made to exit from a small hole (24) in the reactor (12) into a region held at a pressure less than half of the reactor pressure, A supersonic jet is thus formed which impinges upon a surface so that the direction of flow of the gas changes abruptly. The silicon droplets, however, are carried by their large forward momentum onto the surface where they are deposited. The salt vapor is then made to flow away from the depositing area and is passed over cooled surfaces where it is made to condense. Modifications of the basic technique allow the silicon to be collected in a variety of physical configurations including pellet form, crystal form, sheet form and ingot form.
